The United Arab Emirates has significantly strengthened its tax administration system through a series of legislative updates under the Tax Procedures framework. These reforms are not isolated changes. They represent a structured shift toward a more digital, transparent, and enforcement-driven tax system across VAT, Excise Tax, and Corporate Tax.

The framework is built around Federal Decree-Law No. 28 of 2022 on Tax Procedures, supported by multiple Federal Tax Authority decisions and Cabinet-level Executive Regulations issued between 2022 and 2026, including:

• Federal Tax Authority Decision No. 4 of 2022
• Federal Tax Authority Decision No. 6 of 2022
• Issuance of a New Tax Procedures Law – TAXP005
• Ministerial Decision No. 26 of 2023
• Issuance of a New Tax Procedures Executive Regulation – TAXP006
• Federal Tax Authority Decision No. 8 of 2024
• Federal Tax Authority Decision No. 2 of 2025
• Cabinet Decision No. 74 of 2023 (Executive Regulation of Tax Procedures Law)
• Cabinet Decision No. 17 of 2026 (amendments to Executive Regulation)

Together, these instruments define how businesses register, maintain records, undergo audits, submit disclosures, claim refunds, and interact with the Federal Tax Authority (FTA).

Overview of the New UAE Tax Procedures Framework

The updated framework is designed to standardise tax administration and strengthen compliance control mechanisms across all UAE taxes.

What this really means in practice is simple: tax compliance is no longer just about filing returns, it is about maintaining a continuously auditable system of financial and operational data.

Key pillars of the framework include:

• Defined tax audit authority and procedures
• Strict record-keeping and retention obligations
• Structured voluntary disclosure requirements
• Clear refund timelines and eligibility controls
• Expanded enforcement and seizure powers
• Formalised digital communication with the FTA
• Harmonisation across VAT, Excise, and Corporate Tax systems
• Legal validity of electronic and indirect notifications through email, SMS, registered post, smart applications, and even physical posting at business premises (Article 11 of Cabinet Decision No. 74 of 2023)
• Formal payment allocation mechanism allowing the FTA to allocate unassigned payments against older tax liabilities and automatically offset credit balances against outstanding obligations (Article 9)
• Legally binding effect of tax assessments and administrative penalties as immediately enforceable debts upon issuance or notification (Articles 20 and 21)
• Confidentiality framework restricting disclosure of taxpayer information except under court orders, government agreements, international treaties, or authorised requests (Article 28)

A major structural shift is the introduction of clear retention periods and extended audit windows, which can go beyond the standard limitation period in specific situations such as audits, disputes, or voluntary disclosures.

Cabinet Decision No. 74 of 2023: Executive Regulation (Core Operational Rules)

This is the operational backbone of the UAE Tax Procedures system. It defines how businesses must actually comply on a day-to-day basis.

1. Record Keeping Requirements

Businesses are required to maintain structured accounting records that go beyond basic bookkeeping.

This includes:

• Financial statements (balance sheet and profit and loss accounts)
• Payroll records (wages and salaries)
• Fixed asset registers
• Inventory records with quantities and valuation
• Tax invoices, credit notes, and debit notes
• Contracts, correspondence, and supporting documents

The key requirement is not just storage, but audit-ready traceability. Every transaction must be backed by verifiable documentation that allows the FTA to reconstruct tax positions.

2. Retention Periods (Critical Compliance Area)

Retention rules are strictly defined and vary based on the nature of records:

• 5 years for general taxable persons
• 7 years for real estate-related records

However, retention can be extended automatically in certain situations:

• +4 years if a tax audit is ongoing
• +4 years if a dispute exists with the FTA
• +4 years if the taxpayer is notified of an audit
• +1 to +2 years in voluntary disclosure or refund-related cases

What this means is simple: in practice, records may need to be retained well beyond five years depending on compliance activity.

In addition, records may be required to be retained by legal representatives even after representation ends for at least one additional year (Article 3(3))

3. Tax Registration and Updates

The regulation formalises the lifecycle of tax registration:

• TRN issuance or reactivation by the FTA
• Mandatory update of registration details within 20 business days of any change
• Changes include:
  • legal structure
  • trade licence activity
  • business address
  • ownership or operational changes

Failure to update registration data can itself trigger penalties.

4. Voluntary Disclosure Rules

Voluntary disclosure is now tightly structured with strict timelines:

• Must be filed within 20 business days of identifying an error
• Applies where tax liability is underreported or refund claims are incorrect
• Threshold rule:
  • Above AED 10,000 → mandatory disclosure
  • AED 10,000 or below → correction through return or disclosure depending on timing

This creates a strict compliance expectation: errors are not optional to fix, they are time-bound obligations.

Voluntary disclosure is also required where refund claims are overstated, with identical 20 business day deadlines applying (Article 10(2))

5. Tax Agent Framework

The regulation also formalises the tax agent ecosystem.

Key requirements include:

• Minimum education and professional experience
• Licensing and registration with the FTA
• Professional indemnity insurance
• Ethical obligations including confidentiality and compliance integrity
• Authority’s power to suspend or delist agents in case of violations

This ensures that only qualified professionals represent taxpayers before the FTA.

6. Tax Audit Framework

The audit regime is highly structured and enforcement-driven.

The FTA may:

• Conduct audits at its sole discretion
• Issue at least 10 business days’ notice before audit
• Inspect premises, systems, records, and assets
• Access electronic accounting systems
• Seize or copy documents where necessary
• Audits are fully discretionary and cannot be legally challenged by taxpayers (Article 15)
•  The FTA may accompany auditors with additional authorised personnel where necessary (Article 17)
• Occupants of premises are legally obliged to facilitate full access to systems and assets during audits (Article 17)

After completion:

• Audit results must be issued within 10 business days
• Taxpayers can request supporting evidence within 20 business days

What this establishes is clear: audits are not informal reviews, they are legally structured investigations.

7. Seizure and Enforcement Powers

One of the strongest elements of the regulation is enforcement authority.

The FTA may:

• Seize documents and assets during audit
• Copy, mark, or remove records for inspection
• Store or move seized items
• Dispose of perishable goods under controlled procedures
• Sell seized goods through public auction if required
• Seized assets must be formally recorded within 10 business days and a detailed seizure report issued to the taxpayer or relevant custodian (Article 18)
• The FTA may dispose of assets that are perishable or deteriorating and is not liable for resulting losses (Article 18 & 22)

This reinforces that tax compliance is backed by real enforcement authority, not just administrative review.

8. Refund Procedures

Refunds are subject to strict procedural timelines:

• Decision within 20 business days of application
• Payment initiated within 5 business days after approval
• Refunds may be withheld if outstanding tax returns exist

This ensures refunds are controlled within a compliance-first framework.

9. Tax Assessment and Penalties

The law clearly defines enforceable outcomes:

• Tax assessments become legally payable debts once issued
• Administrative penalties are enforceable immediately upon notification
• Penalty breakdown must be clearly documented
• Non-compliance results in structured enforcement actions

10. Tax Crime and Reconciliation Framework

A unique feature of UAE tax law is structured reconciliation in tax offences.

This allows:

• Settlement of tax liabilities before or during prosecution
• Monetary settlement in exchange for case closure
• Full tax and penalty payment plus additional settlement amounts
• Termination of criminal proceedings upon completion of reconciliation
• Reconciliation is legally structured across three stages: pre-trial, trial, and post-conviction, with escalating settlement percentages depending on stage of proceedings (Articles 23–24)
• Instalment payment plans of up to 2 years are permitted for reconciliation amounts subject to guarantees
• Failure to comply with reconciliation terms automatically voids the settlement and reinstates criminal liability

This creates a controlled resolution mechanism for tax disputes and offences.

Key Compliance Obligations for UAE Businesses

Under the updated framework, businesses must focus on:

• Maintaining full audit-ready financial records
• Ensuring timely tax registration updates
• Submitting voluntary disclosures within legal deadlines
• Preparing for risk-based tax audits
• Managing refund claims within limitation periods
• Ensuring correct representation through registered tax agents

Non-compliance is no longer treated as a procedural error. It is treated as a structured violation with defined penalties.

Practical Impact on Businesses

The impact of these regulations is not theoretical.

For UAE businesses, it means:

• Compliance is continuous, not periodic
• Record keeping must be audit-proof
• Tax errors must be corrected within strict deadlines
• Digital systems are no longer optional
• Audit exposure is broader and more structured

This applies equally to:

• SMEs
• Free Zone companies
• Mainland entities
• Multinational groups

Issuance of the New Tax Procedures Law – TAXP005

The Public Clarification TAXP005 explains the implementation of the New Tax Procedures Law and provides guidance on how businesses should interpret its provisions.

Key Features Introduced

1. Unified Tax Procedures Across All Taxes

The new law consolidates procedural rules applicable to:

• VAT
• Excise Tax
• Corporate Tax
• Other federal taxes

This ensures consistency in how taxpayers interact with the FTA.

This unification is supported by the Executive Regulation framework under Cabinet Decision No. 74 of 2023, which applies common procedural standards across all federal taxes administered by the FTA.

2. Defined Limitation Periods

The law introduces a five-year limitation period covering:

• Tax audits
• Tax assessments
• Refund claims

The FTA may still conduct audits beyond this period under specific circumstances, particularly where refund claims are filed near the expiry of the limitation period.

However, the limitation period can be extended automatically in defined cases including ongoing audits, disputes, voluntary disclosures, and audit notifications, which may extend retention and review periods up to an additional 4 years under the Executive Regulation (Article 3 of Cabinet Decision No. 74 of 2023).

3. Enhanced Voluntary Disclosure System

Voluntary disclosures are required when:

• Tax errors affect payable tax
• Omissions result in incorrect reporting
• Refund claims require adjustment

The new system clarifies when voluntary disclosures must be filed and when corrections can be made in subsequent tax returns.

Voluntary disclosure is legally time-bound and must generally be submitted within 20 business days of identifying an error, with strict monetary thresholds triggering mandatory disclosure obligations under the Executive Regulation (Article 10).

4. Strengthened Taxpayer Rights

The law enhances transparency by:

• Defining taxpayer communication rights
• Allowing clarification requests
• Providing timelines for FTA responses

These changes help businesses manage tax risks proactively.

Taxpayer rights also include access to audit-related supporting documents and the right to request underlying evidence used in tax assessments within prescribed timelines under the Executive Regulation.

Federal Tax Authority Decision No. 4 of 2022

Effective from 1 June 2022

This decision established detailed administrative procedures related to taxpayer requests and clarifications.

Key Provisions

1. Procedures for Issuing Clarifications

Taxpayers may request:

• Private clarifications
• Administrative exceptions
• Input tax apportionment rulings

The FTA must respond within defined timelines, subject to receipt of complete information.

If additional information is required, the timeline resets upon submission of the requested documents.

These clarifications are discretionary in nature and may be rejected if incomplete information is provided or if procedural requirements are not met.

2. Response Requirements

Taxpayers must respond to FTA requests for additional information within specified time limits. Failure to respond may result in rejection of the request.

These rules enhance procedural transparency and accountability.

Federal Tax Authority Decision No. 6 of 2022

Effective from 1 September 2022

This decision introduced updated procedures related to tax records and compliance documentation.

Key Impacts on Businesses

• Mandatory record-keeping compliance
• Standardised documentation requirements
• Improved audit readiness standards

Businesses must maintain accurate records supporting:

• Tax returns
• Financial transactions
• Input tax claims

Non-compliance may result in administrative penalties.

These record-keeping obligations align directly with the Executive Regulation requirement that records must be audit-traceable and capable of reconstructing tax positions upon FTA request (Article 2 of Cabinet Decision No. 74 of 2023).

Ministerial Decision No. 26 of 2023

Effective from 22 February 2023

This decision introduced procedural enhancements supporting the new Tax Procedures Law.

Major Changes

1. Digital Communication Requirements

The decision encourages digital interaction between taxpayers and the FTA.

Businesses are expected to:

• Use approved digital platforms
• Submit electronic documentation
• Maintain digital records

Digital communication is legally recognised under the Executive Regulation, where electronic records, emails, and smart systems are valid forms of official notification and submission.

2. Alignment with Corporate Tax Regime

With the introduction of Corporate Tax in the UAE, procedural rules were aligned across multiple tax systems to ensure consistency.

This integration supports:

• Corporate Tax compliance
• Multi-tax reporting environments
• Integrated audit processes

This alignment is part of a unified procedural system under Federal Decree-Law No. 28 of 2022, ensuring consistent audit, refund, and disclosure treatment across VAT, Excise, and Corporate Tax.

Issuance of New Executive Regulation: TAXP006

Public Clarification TAXP006 explains the implementation of the Executive Regulation of the new Tax Procedures Law.

These Executive Regulations provide detailed operational guidance for businesses.

Key Operational Areas Covered

1. Registration Procedures

Businesses must:

• Apply for tax registration
• Maintain updated registration records
• Notify the FTA of changes within prescribed timelines

Failure to update registration details may result in penalties.

Registration updates must be submitted within 20 business days of any change, including legal structure, ownership, business activity, or registered address (Article 6 of Cabinet Decision No. 74 of 2023).

2. Tax Refund Procedures

Refund requests must:

• Be filed within prescribed limitation periods
• Include supporting documentation
• Follow formal submission procedures

The FTA must review and notify taxpayers of approval or rejection outcomes.

Refund decisions are subject to a 20 business day review timeline, with payment initiated within 5 business days after approval (Article 26).

3. Tax Audits

The Executive Regulation defines:

• Audit initiation procedures
• Required documentation
• Taxpayer cooperation responsibilities

FTA auditors may request records and explanations relevant to tax compliance.

Audit selection is fully discretionary and cannot be legally challenged by taxpayers, and audits may include inspection of premises, systems, and physical assets (Article 15 & 17 of Cabinet Decision No. 74 of 2023).

4. Enforcement and Penalties

Non-compliance may trigger:

• Administrative penalties
• Tax reassessments
• Legal enforcement actions

These provisions strengthen enforcement mechanisms.

Administrative penalties and tax assessments become legally enforceable debts upon issuance or notification without requiring further court action (Articles 20–21).

Federal Tax Authority Decision No. 8 of 2024

Effective from 1 January 2025

This decision further enhanced procedural clarity and administrative processes.

Key Updates

1. Clarification and Directive Policies

The FTA introduced structured policies for issuing:

• Administrative clarifications
• Directives
• Binding interpretations

These policies help ensure consistent application of tax rules.

Binding interpretations issued by the FTA are legally enforceable and must be followed by taxpayers unless successfully challenged through formal objection mechanisms.

2. Administrative Transparency

The decision was formalised:

• Processing timelines
• Communication standards
• Documentation formats

These measures improve taxpayer confidence and compliance efficiency.

Federal Tax Authority Decision No. 2 of 2025

Effective from 1 March 2025

This decision updated the FTA’s policies on issuing clarifications and directives.

Key Features

1. Binding Guidance Mechanism

The FTA gained authority to issue binding directives on:

• Tax interpretation
• Transaction treatment
• Compliance methodologies

This reduces uncertainty and enhances legal clarity.

2. Improved Administrative Coordination

The decision strengthens communication between:

• Taxpayers
• Tax agents
• The Federal Tax Authority

These improvements support faster resolution of technical tax matters.

This coordination is reinforced by structured notification rules, including valid service through email, SMS, smart systems, and registered post under the Executive Regulation framework.

Key Compliance Areas for UAE Businesses

Businesses operating in the UAE must focus on several critical compliance areas under the new law.

1. Record-Keeping Requirements

Businesses must maintain:

• Financial records
• Tax invoices
• Supporting documentation

Records must be retained for statutory periods to support audits.

Records must be maintained in an audit-reproducible format, either as originals or verifiable electronic copies accessible upon FTA request.

2. Refund and Credit Claim Rules

Refund applications must be submitted within:

• Five years from the relevant tax period

Failure to apply within this timeframe may result in loss of refund eligibility.

3. Voluntary Disclosure Obligations

Businesses must submit voluntary disclosures when:

• Errors impact tax liabilities
• Incorrect amounts are reported
• Omissions are identified

Failure to disclose may lead to penalties.

Voluntary disclosure timelines are strictly enforced and failure to comply within prescribed deadlines may lead to escalation of penalties and reassessments.

4. Tax Audit Readiness

Companies must prepare for:

• Scheduled audits
